Laura has been in a comfortable yet passionless relationship with Antonio for most of her life. When Sergio, a former high school classmate, and his free-spirited, millennial girlfriend Siena cross paths with Laura and Antonio, they unknowingly revolutionize the lives of everyone within the group of friends. Uncomfortable feelings and desires begin to surface, and Laura, Raquel, and Cris convince their husbands to play a game where each person places their house keys in a bowl and selects another set of keys randomly. The chosen individual must then spend the night at the house of the keys' owner. This game forces everyone to confront who they are and what they truly want from their relationships and their lives.
